Hello. I have recently purchased a 1990 Miata with 125K miles. It is in very good shape for a car built in October 1989. My plan is to use a 1994 5.0L that was to go into my fairlane and install it in the Miata starting next year. Mimi is so much fun to drive as she is, that we want to enjoy the summer before beginning deconstruction in the fall.
